If you succeed, you have some blood in you, and can work on V2 architecture on some other cloud or in your own cage at a DC. This seems like a good bargain for a business that is validating whether they can make money at all, especially a VC-backed startup that is fine with burning cash to prove a concept. Seems like something in-between totally-infinitely-scalable-and-portable-bulletproof-infra and "fake it with spreadsheets and manual work".
